'tv agency?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'great love infusing manager' is the wordplay.
'great' becomes 'sterling' (I can't justify this - if you can you should give a lot more credence to this answer).
'love' becomes 'o' (love means zero in tennis).
'infusing' indicates putting letters inside (to infuse is to fill or enter).
'manager' becomes 'coper' (someone who manages or copes).
'o' put inside 'coper' is 'cooper'.
'sterling'+'cooper'='STERLING COOPER'

'of' is the link.
